online … WebSockets is an efficient, standards-based technology that enables bidirectional communication over the standard HTTP ports 80 and 443. The use of the standard HTTP ports allow WebSockets to communicate across the web through intermediaries.

Client technologies HTML5 Web Sockets provides an enormous step forward in the scalability of the real-time web. As you have seen in this article, HTML5 Web Sockets can provide a 500:1 or—depending on the size of the HTTP headers—even a 1000:1 reduction in unnecessary HTTP header traffic and 3:1 reduction in latency. Jan 22, 2014 WebSocket vs HTTP GET. A streaming WebSocket efficiently pushes messages to clients, whereas the GET interface enables clients to explicitly request messages. Although the WebSocket mechanism is often preferred due to its efficiency, the GET mechanism can be useful for clients that are unable to use WebSockets. Jan 24, 2019 · HTTP has an overhead in the form of headers for every request. Whereas websockets only have this for the initial request (there is some overhead in the messages, but it is minimal).

This article is all about when to use a HTTP instead of a WebSocket (or HTTP 2.0) or vise-versa. When HTTP is better than WebSocket. When evaluating whether HTTP is the better choice, you may find it helpful to think in terms of scenarios. And when it comes to scenarios, these are the ones for which you’ll find HTTP is particularly well-suited.

🔐Optimized security. Being meticulously optimized for speed and memory footprint, µWebSockets is fast enough to do encrypted TLS 1.3 messaging quicker than most alternative servers can do even unencrypted, cleartext messaging. HTTP has an overhead in the form of headers for every request. Whereas websockets only have this for the initial request (there is some overhead in the messages, but it is minimal). Websocket messages are therefore smaller if you send more than one message. One HTTP request and response took a total of 282 bytes while the request and response websocket frames weighed in at a total of 54 bytes (31 bytes for the request message and 24 bytes for the response).

Whereas websockets only have this for the initial request (there is some overhead in the messages, but it is minimal).
